MDM Trouble Report for 2013 Jun 22 Telescope: 2.4m Observer(s): John Thorstensen (Dartmouth) Instrument: Nellie CCD + Buckeye FW Problem(s) Encountered: Nellie wasn't communicating when I started just before sunset -- I had to cycle the power. Luckily, this worked the first time. At one point during the night I had a slew hang very near the target, and it looked as if it were walking away from the target. This is unusual behavior to say the least. The cure was the usual hung-slew cure, namely the software STOP button followed by resending the command. I don't think I'd seen quite this exact variety of misbehavior. ------------------------------ Submitted on 2010 Jun 23 [5:23:38]
